BONE FIXATION DEVICES HAVING A LOCKING FEATURE

摘要

Devices and methods for locking one or more bone screws to a fixation plate. A cam-style locking feature may be disposed in the fixation plate such that, when the locking feature is in a first position, the bone screw is able to traverse an opening in the fixation plate and engage adjacent bone; and when the locking feature is rotated into a second position, an interference between the locking feature and bone screw causes the bone screw to be firmly secured to the fixation plate.
